SFECIPICATION forming part of Letters Patent No. 345,720, dated July 20,1886.

T0 (6 whom it may concern:

Be it known that I, Annnn'r L. PARCELLE, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Vibrating Electric Motors, of which the following is a specifieation.

, The invention has special reference to the class of motor shown in Letters Patent No. 324,152, granted to me August 11, 1885. The details are fully set forth below. This motor, as well as that shown in my patent, is adapted for higher power than the running of telegraph and other light instruments.

In the accompanying drawings, Figure 1 is a plan, and Fig. 2 side elevation, of a motor showing the vibrator-magnets arranged as in my prior patent. Fig. 3 is a transverse section through 1; Fig. 1-, a plan view showing the use of additional or auxiliary vibratormagneis; Fig. 5, a transverse section through Fig. :i-, showing the switch devices. Fig. 6 is a plan view, partly in diagram; and Fig. 7, a side elevation showing a different arrangement of motor or vibrator magnets and power con veying or driving devices. Fig. 8 is a view showing a non-resilient pivoted vibrator havingindependent springs bearing upon it. Fig. 9 is a view of a eenl'rally-pivoted walkingbeam vibrator with accessory springs, and ilOis a view in which the armature on the vibrator is shown as an electroinagnct.

The different novel features of the motor are illustrated detached in the various figures. Of course they may all be combined in one motor, and are intended so to be.

Referring now specially to Figs. 1, 2, and 3, A is the vibrator, which may be secured adjustably or otherwise in its support, and a the transverse arn'iature carried on its end. The motor-magnets I O are arranged opposite the armature or end of the vibrator outside of its curve of vibration, as in my prior patent. In the present instance I dispense with the supplemental springcircuit contacts shown in my patent and employ switch devices only. The special form of switch illustrated in Figs. 1, 2, 3, is as follows: The moving V-shaped switch D is pivoted at its apex in a suitable bearing in the base-board, and. the vibrator A. works Serial No. 171,005. (No model.)

in or between its legs or arms, as clear] y shown in Fig. 3. The upper faces of the two legs of the switch are curved or inclined. downwardly from the inside outwardly, and have seated in them the circuit-contacts c I), through which the circuits of the vibrator-magnets are com pleted. The switch springdingers cb, which rub over the contacts 0 b, are respectively mounted in brackets e f on opposite sides of the pivoted switch-block I), and are adjustabi y secured in the brackets by means of screw thumb-bolts, as clearly shown in Fig. 3. 0b viously, by adjusting the fingers c b the moment of magnetizing and demaguetizing the vibrator-magnets C B may be varied to regulate the amplitude of vibration, or to bring the contacts into the most advantageous position, so as to act most economically as regards consumption of battery-power. The circuits are clearly and unmistakably shown by the diagram in Fig. 1, and description is unnecessary. The vibrator, as in my prior patent, is straddled by the arms of an anchor-lever, G, the rocking of which, through the medium of suitable spring-pawls and a ratchet-wheel, imparts motion to the shaft to be driven. In the present case, however, the vibrator has little or no play in the jaws of the fll1Cl10F-l0\'6l,l)l1li moves it positively in each direction. This arrangement is best adapted for a higher-power motor, and also serves to impart a greater speed to the driven shaft, as there is no lost motion.

Referring to Figs. i and 5, it will be observed that, in addition to the vibrratonmagnet-s C B, I employ an additional magnet, O or 13, placed outside of the magnet O or B. The operation is as follows: As the armature is drawn up to O or 13 the circuit in that magnet is broken and the circuit completed through 0 or 13, as the case may be, so that magnet also acts upon the armature, thus increasing the power and amplitude of the movement. The makes and brakes of circuit are of course so timed as to act on the armature when it is in the position of greatest advantage. The vibrator returns from its eX- treme position by its own resiliency until again acted on by the magnet O or B. More than one additional magnet on each side might be used,- if desired. The vibrator is here shown as driving a rotating'shaft, as in Fig. 3, but in the organization shown in Figs. 4 and 5 I employ a rotating switch or commutator, II, mounted on the driven shaft. The switch is clearly illustrated in Fig. 5. Its metallic hub h, which is connected with one pole of the source of energy, is exposed at four points, the spaces between the exposed sections beingcovered with insulating material, and rotates in contact with the four spring-fingers 1 2 3 4, which are mounted in a post, 11. The fingers 1 2 3 4 may be independently adjustable, so that the moment of magnetization of each magnet may be varied, ifdesired. Thus by changing the period of magnetism of the outer magnets they may be caused to act less vigorously on the armature and the amplitude of vibration will be reduced, or the four fingers may be bodily adjusted in a gang to vary the period of magnctization of all the magnets, and consequentrotary switch shown in Fig. 5.

ly the amplitude of vibration. The legs of the circuit leading to the several vibratormagnets are numbered to correspond with contact-fingers 1 2 3 4, and the running of the circuits will be clearly understood. Thus, assuming that the circuit marked 4 has just been completed, the next will be 1, then 2, then 3, and then 4 again. The rotation of the hub is so timed as to bring a contact-surface on it to the fingers at the proper time. Obviously, an impulse of vibration having'been imparted to the reed or vibrator, the magnets G O B B will continuously drive it. In such an arrangement power may be taken from the rotating commutator-shaft by means of a pulley, H

Referring to Figs. 6 and 7, I have shown a switch device which is the equivalent of the The vibrator in its movement reciprocates a switclrarm,

I, which is provided with uprights i, which embrace the vibrator and travel in a suitable guide, I. The switch-arm is flexible or elastic, as indicated at the pointi, and carries on its end a roller, which is either metal or has its periphery faced with metal. This roller has its bearing on a downwardly-projecting pin, and travels in a curved socket or track, 9', in a block of insulating material, J. An oval-shaped conducting-post, 3', stands in the center of the socket j, and is connected with one pole of the source of energy. The wires leading from the magnets OB are respectively connected with spring contact fingers c b, mounted on the insulating-block J, and projecting into the path of the roller or contact maker on the end of the arm I. As the arm I is reciprocated by the vibrator the contact-maker or roller 13" travels around the conducting-post j, being deflected in the b and the post j, in contact with both the finger and post, and alternately completes the legs of the battery-circuit, which include the vibrator-magnets. The block J is shown as sliding in guides J, so as to accommodate itself to varying degrees of amplitude of the vibrator, and may be steadied by springs J secured on the bed-plate and bearingagainst each end. Instead of placing the vibratormagnets opposite the end of the reed, I may locate them above or below, or both above andbelow,on each side of the center of vibration, with their poles in a plane parallel with the plane of vibration and opposite the outer end portion of the reed, as clearly shown in Figs. 6 and 7. In that case the armature or armatures A may be arranged on the outer endportion of the reed, and may be parallel ,with'it, as shown. The circuit-connections are the same as with the other arrangement. The magnets O B may be arranged on one side of the vibrator only-i. 0., either above or below; but I prefer to employ magnets X, placed opposite C and B,respectively,to act on the opposite side of the armature, as such arrangement gives better and more economical working. Of course the'upper and lower magnets on each side may be included in the same circuit. As indicated by dotted lines in Fig. 6, additional magnets arranged on the same principle as those in Fig. 4 may be used. The legs of the circuit including them willrun to additional spring contact-fingers to be placed on the block of insulating material J in proper relation to the traveling circuit-maker 13". With this construct-ion the vibrator has the same freedom of motion, and may be drawn beyond the poles of the vibrator-magnets. The distinguishing feature of my in vention, both in this form and as shown in my patent, is this capacity of the vibrator, which is of courseduc to the novel relation ofthe magnets to the vibrator. In these figures I have shown another manner of taking power from the vibrator. A pitman, L, sliding in a suitable guide, L, is provided with adja cent vertical lugs having adjustable screws, between which the vibrator is clamped. The pitman carries at its end two racked arms, one of which gears with the upper side of a pinion, m, and the other with the under side.

of a. pinion, 0. The pinion m is fast on a shaft, 01, which has one bearing in a suitable post and the other in the end of the main shaft 1?, and carries a friction-disk, m, which rotates within the open face of a flanged disk or drum, Q, fast on the end of the shaft 1.

The disk at is provided with friction clutchblocks m pivoted in sockets therein, andso arranged either to be thrown out by springs or drawn out by friction to clamp the disk understood, and more elaborate illustration is tion of the shaft Iin one direction.

also rotates within the drum Q, andis equipped with similar clutch devices. Obviously the main shaftP will be continuously rotated in the same direction, the movement of the pitman in both directions acting to produce the rota- As there is no lost motion of the vibrator between the screws carried by the pitman, it follows that the greater the amplitude or vibration the higher will be the speed of the driven shaft 1?. This is also true of the ratchet-and-pawl arrangement shown in Fig. 3, as the greater the amplitude of vibration the greater the number of teeth on the ratchet-wheel which will be traversed by the pawls. The vibrator, instead of being resilient, may be rigid and pivoted and have springs A, either plate or coiled, acting against each side of it, as clearly shown in Fig. 8.

In Fig. 9 I have shown a walking-beam vibrator pivoted at its middle and having an armature at each end. Magnets C B are an ranged to act on each end in conjunction with each other, as will be plain. The vibrator is returned to its central position by the action of the accessory springs A". Power may be taken from the vibrator in any of the ways shown or in any suitable manner.

The armature may be an electromagnet, as illustrated in Fig. 10. In that case the cir cuits may remain the same as in Fig. 1, with the addition ofthc armature circuit, as follows: One insulated wire, .11, leading from the armature-coil may be carried along the vibrator to its support, and then connected with the minus wire of the battery, as shown. The other wire, m, which may also be carried along the vibrator, is connected with both posts 6 fof the spring-lingers c 7). In this arrangement the armature and field magnets are connected in are; but any other arrangement ofcircnits may ofcourse be used. For instance, the coils may all be connected in series. or the armaturecoil and iicldcoils might be connected. in different circuits. It is also of course so that the opposite lield'coils may each have independent circuits. The running of the circuits in Fig. It) will be plain.

I have now described the several features of my invention. While they are illustrated as embodied in a practical working manner, I do not of course limit them to the specific structures shown, as, doubtless, variations may be made without departing from the principles of the invention.

Motors constructed in accordance with my invention may be used for all the purposes to which electric motors are applicable. They run with a smooth and regular action, and are economical in construction and consumption of battery-power. These advantages are due, among other reasons, to the facts, first, that the power is applied at a distance from the fulcrum or fixed point of the vibrator and a distance from the load, thus giving a large leverage in favor of the motor; and, second, because of the great absence ot'induced conn tor-currents in the coils and circuits.

It should be understood that in my improved motor the rate of vibration remains the same. and that variation of magnetic attraction affcets the amplitude only.
